I am having a feeling of deja-vu here
Personally i think that elusive targets should never return, it would go against the purpose they were designed for, one shot simple contracts, there really ain't much to replay there, your first shot at them which makes it memorable is the whole point, maybe the "story" dialogue would be missed but most of it is filler and forgetable.
That said i do think the rewards should be available to unlock some other way in the future, for people who are latecomers, that never heard of the game,don't care for it now, or join in years down the line, if i was one of them i don't think i could play the game without the blood money suit! No gloves is a blasphemy!!
This brings me to the point that i think there should be some sort of economy system or upgraded unlock choice system but thats going off-topic.
Point is, the elusives are an incentive to buy the game now, join in&have fun, chances are if i didn't find the elusives so fun and intriguing, i would have stuck to my original plan bought the game with the disk release,
Yes, i do think they could be better and the wait between them could be shorter. but its one of the few if not only "live" updates that brings me back
For people worrying they wont get enough, trust me, Season 1 is concluding in January, there will be lots more coming after that, i see no reason to worry.
